ABSTRACT:
A control valve in which the bonnet is removably fixedly attached to the valve body by a retained bolt and slot arrangement in such a way as to fix the marginal edge of the diaphragm main valve therebetween. The diaphragm defines with the bonnet a control chamber having an inlet control passage leading thereto from the valve body inlet and an outlet control passage leading therefrom to the valve body outlet. A control valve seat in the outlet valve seat is controlled by a solenoid plunger valve element in such a way as to afford either manual or electrical solenoid operation by virtue of a manually movable member mounting the solenoid assembly on the bonnet. An adjusting knob member is mounted by a snap fit on the bonnet in laterally offset relation with respect to both the main valve and the solenoid assembly. An adjusting member is snap fitted in fixed relation to the knob member and has a meshing gear relationship with a valve engaging element threaded on the interior of the bonnet so as to move toward and away from the main valve in response to turning movements of the knob member.
